FSM: On free vs. proprietary

There is currently a competition going on between two types of business model. Each have their strong advocates, supporters and enemies. Flame wars have raised the temperature of various communication channels. So called "independent" analysts have thrown in their lot with one, singing the praises of their choice, while condemning to the depths of Hades the other, regardless of the facts. In short, it's good old fashioned fun for all and sundry.

In the red corner their is the Proprietary Model of building software. Microsoft, with its legion of followers, is a perfect example of this model in action.

In the blue corner is the Free Software Model of building software. GNU/Linux and its army of supporters the epitome of that model at work.

Putting my prejudices aside (I am a strong supporter of the free software camp), I discovered there are both advantages and disadvantages to each.
